Description:Excerpt from Proceedings of the American Railway Engineering Association, 1983, Vol. 84 Innovative methods were proposed to ventilate the longer tunnels by using a system of intermediate air shafts, gates and fans. The design considerations for the major components of the ventilation system are briefly addressed and the problems of accessability of equipment in remote areas, and the design of tunnel gates are described. Problems associated with train operation in the tunnels are discussed, with particular reference to the effect of flushing time on overall train cycle times. Various methods of reducing cycle times for given flush times are discussed, and graphical techniques currently under development are used to determine Optimum solutions. Consideration is also given to the transient locomotive cooling problems associated with entry to and exit from the tunnels. Finally, consideration is given to methods to determine the capacity of a railway line which passes through several ventilated tunnels, in order to determine the optimum operating mode for such a network.
